My invention relates to a dishwashing maas Well as dish rack 20 shapedto rest on the ch ne and more particularly to a machine -inclined bottom11. wherein the dishes are washed by splashing The water spraying deviceillustrated in the water preferably by means of a motor. Figure 3,consisting of a tube 21, is prefera- The obJect of my invention isto.produce bly formed as shown although changes could 55 a veryeffective machine, highly sanitary and be made which may be aseffective. So that economical 1n use. 4 the water will be sprayed whenthe cover of In the accompanylng drawlngs, forrnlng the container isclosed, it is mounted to be part of the following description, 811111raised and lowered at the same time as the reference Symbols. refgl' tosame Parts cover. To effect this purpose, a T elbow 22 throughout theseveral views. is connected to the spraying tube 21. The Flgm'e 1 alongltudlnal sect10ha1 l end of elbow 22 is conical in shape and serves171011 of a dlshwashmg 'machlhe cohstmcted as a spigot for a valvecontrolling the water.

What I claim, is

In a plate and dish washing machine, a container, a sp 'aying tubeswingingl'y mounted therein, said tube shaped to form a double loop, a Tcoupling connected to one side of said p, an elbow forming part of saidT coupling, a valve connected to said coupling, comprising a spigotdisposed so as to close the valve when the spraying tubev is raised, andmeans to connect said valve to a supply of water.

In testimony whereof, I have hereto aflixed my signature, this 10th dayof August, A. D. 1927, at the city of Halifax, in the Province of NovaScotia, Canada.
